I've stumbled into a rather dense board layout with several painfully placed via fanouts in place. I now need to replace the vias with slightly smaller padstacks due to density and spacing issues. I can not locate the mode/function to interactively change the via padstacks on the already placed and routed fanouts! I have found references to such a mode and operation in user guides, but none apparently work for the PCB editor (apparently only the router). I DO NOT want to spend hours painfully deleting and re-doing the fanouts to get smaller via padstack selections. None of the "mode change_via" commands appear to work. I'm running Allegro "Performance" Editor 16.6 hotfix 64. If anyone can educate me on how to "change vias" I would be extremely grateful. (Yes, I've "unfixed" the via fanouts that get implemented by default,. so I can manually slide and edit the traces one by one. I've also edited the CM to allow smaller via padstacks and such). Thanks in advance!
